1. The famous shia historian yaqoobi recorded in his book tareeq yakhoobi:

That year umar ibn al khattab sent the proposal to marry kulsum bint ali to Ali bin abi talib, her mother was fatima bint rasool allah(saw), hazrat umar said I want to marry umme kulsum because I heard prophet(Saw0 saying: “Every tie of kinship, and every association will be cut off on the Day of Qiyamah, except my kinship and my association.” [‘Umar said,] “I have had the companionship of Rasulullah r ; I would like also to have this kinship, so he )hz ali) married his daughter to him and the decided the mehr to be 10,000 dinar.( tareeq al yakhoobi, vol 2, page 149, 150)

similarly tabari has recorded the similar narration in , “tareekh al ummam wal malook” vol 5, page 16, misr )

Ibn al atheer noted this in “al kaamil” vol 3, page 29 , darul kitab beirut)

Ibn saad noted this in “tabqaat al kubra” vol. 8 p. 338, Dar al-Kutub al-‘Ilmiyyah, Beirut.

similar abu al fida in his tareek and other renowned historians have recorded this incident.

In this work(I.E Furu’ al-Kafi ) the author has documented at least FOUR traditions to the Imams which affirm the marriage of Umm Kulthum to ‘Umar. In fact, he has devoted the 23rd chapter in the Book on Marriage (Kitab an-Nikah) in Furu’ al-Kafi to the marriage of Umm Kulthum (bab tazwij Umm Kulthum). Two of the four traditions are contained in this chapter, while the other two are found in a related chapter on where a widow whose husband has died should spend her waiting period, or ‘iddah (bab al-mutawaffa ‘anha zawjuha al-madkhul biha ayna ta’taddu wa ma yajibu ‘alayha).

2. Mu’awiyah ibn ‘Ammar says: I asked him about a woman whose husband died: Should she spend her ‘iddah in her house, or where she wants to? He replied, “Where she wants to. When ‘Umar died, ‘Ali u came and took Umm Kulthum to his house.” (Furu’ al-Kafi, vol. 6 p. 117)

3. Sulayman ibn Khalid, who says:I asked Imam Ja’far as-Sadiq about the woman whose husband has died: Where should she spend her ‘iddah? In her husband’s house, or where she wants to? He said: “Where she wants to. When ‘Umar died, ‘Ali u came, took Umm Kulthum by the hand, and took her to his house.” (Furu’ al-Kafi, vol. 6 p. 117)

Abu Ja’far al-Tusi relates from imam Ja’far and he from his father imam Baqir :
He said: “Ali’s daughter Umme-Kulthum and her son Zaid bin Umar bin al-Khattab, died at the same time. No one knew who died first. Therefore none of them was made the inheritor of the other, and their funeral prayers were offerred simultaneously.(tehzeeb al ahkaam, kitab al meeras, chapter meeras al garkhi wal mahdoom, vol 9 , page 262)

As for giving his daughter in marriage, we have mentioned the answer to this in the book ash-Shafi in detail, and that he only consented to give his daughter after he had been threatened and menaced and after there had been altercations at length. ( Tanzih al-Ambiya wal-A’immah page 141, iran)

The Prophet married one of his daughters to Uthman and the other to Abu-al-As bin Rab’i, and both of them were non-Hashmis. Similarly Ali married Umme-Kulthum to Umar. Abdullah bin Umar bin Uthman married Fatima, the daughter of Hussain and Musa’b bin al-Zubair married her sister Sakina. All of the were non Hashmis. (Masalik al-Ifham “Sharh Shara-il-Islam”, Chapter Lawahiq-al-‘Aqd, Vol.1, Iranian Edition 1282 A.H)

18. Umar bin al-Khattab sent a messenger to the emporer of Rome. Umar’s wife Umme-Kulthum bought a (bottle of) scent which was worth a few dinars. She poured it into two bottles and sent it as a present to the wife of the Roman emperor. When the messenger returned, he brought with him two bottles filled with jewels.

When Umar cam into her room, he found the jewels scattered all over the place.

He asked her: Where did you get them? Umme-Kulthum explained to him (the whole story). Umar held them (in his hands) and said: all of the belong to the Muslims.
She inquired: how? they have been sent to me in exchange for my present.

He replied: I leave the decision to your father.

Ali explained: Your portion out of it is the value of just one dinar; the rest of it belongs to the Muslims as it is the messenger of the Muslims who has brought it”,.(Ibn abi al-Hadid “Sharh Nahj-ul-Balaga”, Vol.4, P.575, Published in Beirut 1375)
